Recently I have been driving my 1993 4-cyl and have a complete loss of power. Have to wrestle it over to the side of the road, no power steering, brakes, etc. Engine cranks back up and I go again. Sometimes it happens several times every 2-3 minutes. First started occasionally and now occurs with great frequency. I'm afraid to head out anywhere any more. I suspect an ignition system problem, but don't know. Think it could be the PCM ? Anybody else experience this weird thing or got any ideas ??

had same sort of problem w/my '93 soon after purchase... took back to dealer... no answers... checked harness... found broken clip on wire to coil... vibrations would loosen it... trashed coil for Accel Computer Coil... problem solved! Look REAL close at harness, making sure all connections are solid... don't start throwing parts at it 'till you check the small stuff.

As was said in previous replies, check all connections first. If all check OK, run your computer codes, the PCM may diagnose the problem for you. You didn't specify if just the engine stopped running or total electrical was lost. If just the engine quit, a Crank Position Sensor on its way out will cause the problem you describe.

Actually the power loss was to the engine and power (such a steering, brakes. etc.) With the engine still turned off you could turn on the lights and they were working. I didn't think to check the radio or fan, etc. Really appreciate all the great replies - big help - these responses at least give me a direction or two. Thanks again - folks.

My 1990 4.2L just started doing the same thing. Replaced starter (for other reasons), coil (since it was cheap) and distributor. Still same problem. Runs, then stops after minutes or hours. May not restart. Thinking ignition module. If so, where is it located? Any help would be appreciated. Thanks

I had the same exact symptoms as you, luckily I replaced the Ignition Control Module First, and save a lot of money. It is located under the Radiator overflow tank. You have to remove the tank to get at it, two bolts. Then it bolts through your fender well, those bolts are removed from the fender well side, three of them. The module costs around $20, and is actually from a Ford. I know a few Ford guys that keep an extra in their glove compartment. You might have to splice different plugs in, other than that its a twenty minute job.
Any questions, PM me.
